Abstract (en)

[origin: EP3834920A1] The invention discloses a dynamic detection system and method for the contact angle of a gas purification membrane, wherein the dynamic detection system for the contact angle of the gas purification membrane includes a light source, a gas purification membrane stage, an imaging system, a computer, and a supporting platform; the light source, the gas purification membrane stage, and the imaging system are linearly fixed on the supporting platform, and the imaging system is connected to the computer; The gas purification membrane stage includes a loose flange, an upper fixed flange, a separation net, a cylinder, a gas outlet, a desiccant, a lower fixed flange, a blind plate, a gas flow controller, a buffer tank, an induced draft fan, and a differential pressure sensor. The detection system can measure the contact angle of the membrane surface in the state of gas filtration and complete the dynamic detection of the contact angle of the gas purification membrane.
